I have noticed quite a fall in the Sigma 100-300mm prices lately, they struggle to fetch 500/550 these days on Ebay and I think the 150-450mm is likely to hit them even further.

Is that why you snapped one up at even lower price today ?
K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

You wouldn't have if you had the chance?

On the downside that was money I had put aside to go towards a K-3II for Yeovilton and Fairford next month.

Haven't sold my own as yet anyway (got it for less than 600 a few years ago, so not "lost" a lot so far!) - so probably not

As you say, you already have one .. I don't (at the moment)

It gives me a nice warm feeling knowing that there are other people on here that are more concerned about what I buy than even I am.

Anyway, back to the Pentax 150-450 F4.5-5.6 vs Sigma 500 F4.5 vs Pentax 560 F5.6 thread. ....

Now the lens is in my possession, I will do a good test run and put up more pictures as and when.

Look forward to it, if you can get the same sort of quality from the zoom as you do from the prime then I think it will have been a worthwhile trade.

Did you PX the 500mm or keep it in the end?

The 500 has gone.

says the man who's owned three copies of every single Pentax lens made

I am always interested to hear how you get on with the 150-450 Mike, it makes more sense to hear the opinions of the people who use the equipment on a regular basis than those who have lenses passing by their desk at an office in London or Peterborough every week....

Did you not try the 560mm

I have tried the 560 a few times and can't fault it. I did not test it yesterday unfortunately. It was out of my budget and lacked the versatility. My main aim was to find out what the 150-450 has to offer compared to my Sigma 500. I shouldn't have added it really. Ah well, i am sure some of he other members will be doing a comparison soon. Sorry about that.

Thanks for this. As a wildlife photographer I am going through the same questions as most others. Every lens generally seems to perform within its budget range. I have found the Sigma 150-500 excellent wide open at 500mm but no better (perhaps slightly worse) than the 300mm DA* + 1.4x TC. My friend has that SIgma on his Canon and it is even better although another friend's is not so good. Are we seeing batch difference in lens manufacturers or difference in techniques? In my opinion these days absolute image quality isn't the deal breaker in the mid price range. With better sensors, the removal of the anti-alias filters and decent software the IQ is often there. I get back yet again to the speed of locking on and subject tracking with Pentax DSLR's. I can get it with DA*300 +1.4TC or DA* alone but having just got back from Bempton shooting relatively easy Gannets I can assure you that my friends' Canons and probably other's Nikons were getting the harder ones with more success although the ones I got are fine IQ wise, or at least to my expectations.
So what I want to know and I'm sure others do is what is the speed of focus and tracking ability of the 150-450 compared to a DA* 300 and DA*300+1.4TC which is more or less the focal length and price range competitor in Pentax range.
In the meantime I am going to hire a Nikon lens and fit to my recently acquired D5300 body and borrow my friends' Canons and find out for myself if this tracking thing is real or a myth!

First outing with the 150-450 to blow off some steam from work

The AF tracking seems a bit slow but it might just be me. Will do the AF fine tuning this wkend and get back with some more photos.

The images are not straight off the camera.
